CHRISTOPHER HAYES, OF J UNEE, NEW SOUTH WALES, AUSTRALIA.

OSCILLATING PROPELLER.

SPECIFICATION forming part of Letters Patent No. 705,348, dated vJuly 22, 1902. Application filed November 23, 1901. Serial No. 83,411. (No model.)

To all whom, t may concern:

Be it known that I, CHRISTOPHER HAYES, a subject of the King of England, residing at Junee, in the county of Olarenton, New South Wales, Australia, have invented certain new and useful Improvements in Life-Boats and l do hereby declare the following to be a full,` clear, and exact description of the invention; such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to life-boats, but more particularly to the propelling mechanism, and has for its'object to provide a boat which is simple in its construction andV com posed'of a minimum "numberof parts.4

My invention'consists'in the `novel arrangement of a life-boat` and' in the propelling arrangement.

My invention also consists in certain other novel features of construction and combination of parts, which will be hereinafter fully described, and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is an elevation of a life-boat constructed in kaccordance with my invention.lv Fig. 2 is a cross-section taken on the lines 2 2' of Fig. 3. Fig. 3 is a vertical section along the lines 3 3 of Fig. 1. Fig. 4 is a fragmenl tary sectional view of theafter portion of the boat, showing the propelling arrangement. Fig. 5 is a transverse section taken on the lines 5 5 of Fig. 4. Fig. 6 is an elevation of the gearing for the propelling mechanism. Fig. 7 is a vertical section taken along the lines 7 7 of Fig. 6. Fig. 8 is a vertical section taken along the lines 8 8 of Fig. 6. Fig. 9 is a detail plan view of the spool and cable xandpro-l peller-post lever. l Y

Like numerals of reference indicate /the same parts throughout the several figures, in Which-` 1 is a boat; 2, thekeel, composed of angleirons 3, securely bolted or riveted together. The body or planking of the boat is preferably of iron or steel, secured in thefordinary manner to the ribs 4.

5 indicate water-compartments upon'wliich the oor 6 is formed. I provide seats or bunks 7 above said floor, and I provide a cabin or covering S over the entire length of the boat,

ble-looped k:bling a tiller. a cable 23, which passes outwardly over two having a suitable door and Windows or portholes.,v

Right aft the skeg 9 I provide a bracket 10, within the end of which the rudder-post l1 is seated. Forward'of said rudder-post I provideafpropeller-po'st 12, towhich is securely bolted uthedouble-looped piecc4l3.

14 indicates my propeller, formed substan` -tially like'a fish-tail and constructed of a springy steel core l'anda sheathing of copper or other suitable metal 16. It will be noticed byreferringfto Figs. 1, 4, and 5 that there is a vertical space oropening 17 in said sheathing for the purpose of preventing the sheathing from crackingby reason of the elasticity of the` inner core..

I providewasquare'bolt 1S through the dou- A piece 13, around which the propeller-'n'is secured.

Bolted to the bracket forward of the propeller-post are two spring-buffers 20, extending aft horizontally and parallel. Around said buffers opposite the square bolt and within the loops of the double-looped piece I provide a band 2l, through the top and bottom of which passes the square bolt.

Securely 'fastened to the top of the propeller-post is al lever-arm 22, closely resem- Attached to said lever-arm is pulleys 24, then forwardly over two pulleys 25,'thence inwardly to around the drum or spool 26,-Fig. 9.

Referring now to Fig. 6, it will be seen that the drum or spool 26 is secured ou a shaft 27, which is journaled in three standards 28, 29, and 30. Keyed on` said shaft are the cogs 31', and 32,having teeth onjonly half their peripheries, thef'toothed portions of the cogs beingon ,opposite sides, as shown in Fig. 6.`

Journaled inrthe standards 28, 29, and 30 is the power-shaft 33, which vcarries a fiy-wheel 34 and a pair of cogs 35 and 36, identical With cogs 3l and 32. Journaled in the standards 29 and 30 is a shaft 37, carrying ahcog-wheel 38 intermediate the'cogJwhee-ls`32 and 36 and meshing therewith.

Having' thus described theseveral' parts of Iny invention, its operation is as follows: The 'power-shaft is turned by any approved means,

which of course causes the cogs 35 and 36 to revolve. As said cogs revolve, we will sup- ICG pose in the direction of the hands of a watch, said cog 35 will mesh with cog 31 and turn said cog half a revolution. Cog 36 being on the same shaft as cog 35 also turnsin the direction of the hands of a watch, but does not mesh with the intermediate cog 38 by reason of the smooth portion of its periphery. While, however, cog 3l'is being turned half a revolution in the direction contrary to the hands of a watch, cog 32, being on the same shaft, is also being turned half a revolution in the same direction. When therefore cogs 3l and 32 have completed their half-revolution in the direction contrary to the hands of the clock, the cog 36 has completed its half-revolution in the direction of the hands of a watch and commences to mesh with the intermediate cog 38, which intermediate cog meshes with cog 32 and reverses the direction of said cog 32, cog 3l being on the same shaft as cog 32 is also reversed and is free to turn one half-revolution in the same as cog 35, by reason of the smooth portions of their peripheries coming together. When however said cog 31 has turned half a revolution in the direction of the hands of a watch, they are again in the position shown in Fig. 7, and the cog 35 meshes with the said cog 3l, and again reverses said cog 31 for half a revolution, thus the shaft and drum or spool, is turned first one way for half a revolution and then the other way.

To refer now to Fig. 9, it will be obviously seen that the propeller-post lever is reciprocated by the winding and unwinding of the cable on the drum or spool.

To refer now to Fig. 4, it will be seen that the propeller or fan is thus thrust to first one side and then the other and each time comes in contact with one of the spring-buffers, which helps to force the fan back against the water, and thus give headway to the boat. By reason of the iiexible fan or propeller the same resembles a fish-tail when in operation and is more powerful than if the same were stiff and rigid.

Having thus described the several parts and the operation of my invention, I do not wish to be understood as limiting myself to the exact construction as herein set forth, as Various slight changes may be made therein which would fall within the limit and scope of my invention, and I consider myself clearly entitled to all such changes in form and construction. y

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

l. Propelling mechanism for life-boats or the like consisting of a fan composed of springy core, a sheathing on either side of the same, having a space or opening between the plates thereof, a propeller-post, a doublelooped piece secured thereto, and carrying said fan, spring-buffers on either side of said fan, a band encircling said spring-bui'ers and carried in said looped piece, a mechanism for operating said fan, substantiallyas described.

2. Propelling mechanism for life-boats or the like consisting of a fan of a springy core, a sheathing on either side thereof having a space or opening between the plates of said sheathing, a propeller-post supporting said fan, spring-buffers secured on either side of said fan, and mechanism for operating said fan, substantially as described.

3. Propelling mechanism for life-boats or the like consisting of a fan composed of a springy core, a sheathing on either side thereof having a space or opening between the plates of said sheathing, means for supporting said fan,and means for operating the same, substantially as described.

4. Propelling mechanism for life-boats or the like consisting of a fan composed of a springy core, asheathing on either side of said core, having a space or opening between the plates of said sheathing, and means for operating said fan, substantially as described.
